Referring to fig. 1 to 6, the present embodiment provides an auxiliary tool for replacing a transformer respirator, which includes a horizontal plate 1, a supporting frame, a guide rod assembly, and a lifting device.

The horizontal placement of diaphragm 1, diaphragm 1 can be with the fixed welding of stand 3 of respirator 2, and this embodiment adopts at diaphragm 1's left end welding engaging lug 4, makes the stand insert and forms detachable connection in the engaging lug, has both made things convenient for this appurtenance dismouting maintenance, also can conveniently install appurtenance in the suitable position of stand 3 according to actual conditions.

The guide bar subassembly includes chuck 5 and guide bar 6, it has the connecting hole to go up chuck 5, it establishes through connecting hole slip cover to go up chuck 5 on diaphragm 1, through removing go up chuck 5, conveniently adjust the distance between guide bar subassembly and the respirator 2, the front of going up chuck 5 is provided with spacing screw, spacing screw female connection has stop screw 7, will go up chuck 5 position adjustment back, screws stop screw 7 alright fix last chuck 5 on diaphragm 1, guide bar 6 is vertical to be welded in the lower terminal surface of last chuck 5.

The support frame includes connecting plate 8 and sleeve 9, the one end of connecting plate 8 is provided with the peripheral assorted notch 801 of the mounting flange dish of respirator 2, the one end opening part threaded connection that notch 801 kept away from sleeve 9 has locking screw 10, and it is fixed with the mounting flange of connecting plate 8 and respirator through locking screw 10, the other end of connecting plate 8 with sleeve 9 integrated into one piece,

sleeve

9 and 8 sliding sleeve of connecting plate are on guide bar 6. The inner diameter of the sleeve 9 is slightly larger than the outer diameter of the guide rod 6, so that the sleeve 9 can slide on the guide rod 6 conveniently, and the flexible connection can be adjusted conveniently when the flange plate and the mounting flange are connected through bolts.

The lifting device comprises a base 11, a motor 12, a threaded rod 13, a threaded sleeve 14 and a hinged frame, the base 11 is a square bottom plate, the base 11 is welded at the lower end part of the guide rod 6, the motor 12 is arranged on the base 11, the output end of the motor 12 is connected with the threaded rod 13 through a coupler, the threaded sleeve 14 is sleeved on the threaded rod 13 in a matching manner, the hinge frame comprises two hinge units, the two hinge units are connected between the threaded sleeve 14 and the support frame, and both are centrally symmetrical with respect to the threaded rod, each of said articulation units comprising a first link 15 and a second link 16, one end of the first connecting rod 15 is hinged with the upper end surface of the threaded sleeve 14 in a pivot mode, the other end of the first connecting rod 15 is hinged with the middle of the lower end surface of the second connecting rod 16, one end of the second connecting rod 16 is hinged with the front pivot of the lower end of the sleeve 9, and the other end of the second connecting rod 16 is hinged with a vertical rod 17 welded on the upper end surface of the base 11.

The use principle of the transformer respirator replacement auxiliary tool provided by the embodiment is as follows:

when the device is disassembled: firstly, the motor 12 rotates reversely, the threaded sleeve 14 moves upwards along the threaded rod 13, the hinged frame is under the action of the threaded sleeve 14, the support frame is gradually jacked upwards along the guide rod 6, the notch 801 is aligned with the mounting flange, then the upper chuck 5 is adjusted, the notch 801 of the connecting plate 8 can be attached to the circumferential surface of the mounting flange, then the locking screw 10 and the limiting screw 7 are screwed, the flange plate and the bolt on the mounting flange are taken down, then the motor 12 rotates forwards, the threaded sleeve 14 moves downwards along the threaded rod 13, and the hinged frame is under the action of the threaded sleeve 14, and the support frame with the respirator 2 is gradually moved downwards to a proper position along the guide rod 6 for maintenance.

When installed: the motor 12 is rotated reversely, the support frame is jacked up by the hinged frame, so that the respirator 2 rises to the height of the flange plate along with the support frame, and then the flange plate is fixedly connected with the mounting flange through bolts. Locking screw 10 and stop screw 7 are then loosened and upper jaw 5 is moved away from the respirator, completing the installation.

According to the content, the utility model discloses avoid the heavy respirator of manpower lift, alleviateed maintenance personal's work burden greatly, reduced the emergence of incident.

Because the flexible connection that the inner diameter of the sleeve 9 is slightly larger than the outer diameter of the guide rod 6 is adopted for the convenience of installation, but because the respirator on one side of the connecting plate 8 is heavy, the sleeve 9 can deviate towards one side of the respirator 2 under the action of the gravity of the respirator 2 in the process of changing the respirator 2 for lifting, so that the sleeve 9 is abutted against the guide rod 6 and the abrasion of the guide rod is further caused in the lifting process, in order to prolong the service life of the guide rod 6 and the sleeve 9, two rows of vertical threaded holes are symmetrically arranged on the left side wall and the right side wall of the sleeve 9, adjusting rods 18 are connected in threaded connection with the threaded holes, one end of each adjusting rod 18, which faces towards the inner side of the sleeve 9, is pivotally connected with a guide round wheel 19, when the respirator 2 is lifted up and down, the adjusting rods 18 are adjusted to enable the guide round wheels 19 to be in contact with the, the service life of sleeve 9 and guide bar 6 is prolonged, when bolted connection flange dish and mounting flange, adjustment pole 18 is adjusted, makes to have the clearance between direction round wheel 19 and the guide bar 6, but sleeve 9 is under the effect of respirator 2, and sleeve 9 and guide bar 6 contactless, so both conveniently installed ring flange and mounting flange, also do not take place the extrusion between sleeve 9 and the guide bar 6.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
